Hose for water, sera 45063 (sera) — gray 16/22 mm, 2.5 m

Water hose from sera in gray, 16/22 mm (inner/outer diameter), 2.5 m long. The hose is designed for general water transfer tasks such as filling, draining and circulation in aquariums, garden equipment and small plumbing connections. It is flexible and free from harmful substances, allowing a safe connection to filters and pumps that use compatible connectors.

Advantages

The sera hose is elastic and easy to route in confined spaces, resistant to kinking under normal handling and free from harmful plasticizers. Its standard 16/22 mm dimensions make it compatible with common aquarium and garden fittings, and the 2.5 m length provides a ready-to-use section for many routine maintenance tasks.

• Filling and draining aquariums
• Connecting to filters and pumps with compatible connectors
• General water transfer for garden tools and small plumbing jobs
